Both hailed from the war torn city of Belgrade. Both became famous in their home country. Both wanted to be the best.

With few other compatriots, isolation combined with a singular goal could have bonded these young women together. The Italian and Czech Fed Cup teams are shining examples of on-court camaraderie in an individual sport. Off the court? The guest list at Elena Dementieva’s wedding was a “who’s who” of Russian tennis (Vera Dushevina caught the bouquet).

Yet, there is something about countries that boast only two talented players. Perhaps that it serves as a microcosm for the game itself, the idea of a dual between two players and only one can emerge victorious, intensifies what could otherwise be a friendly rivalry. Whatever the reason, like Belgians Kim Clijsters and Justine Henin before them, the relationship between Ivanovic and Jankovic was always cool at best. Never overtly friendly, the two had ways of reminding fans and media where the two women stood with one another.

After scoring a win over her rival in Madrid a few years ago, Jelena was seen mocking Ana’s signature fist pump:

Upon seeing it, Ana quipped, “…Sport doesn’t build character, it shows it.” Far from contrite, Jelena defended the gesture and struck out against players who fist pump “in the player’s face, and especially after not winning a point [but] after your opponent missed an easy ball, I don’t think that’s fair play.”

For all of their differences, Ana and Jelena ended up having two fairly similar careers.

At their peaks, they fought for the No. 1 ranking at the 2008 French Open. Jankovic squandered a third set lead and Ivanovic went on to win her only Slam title. From there, she promptly entered a slump that persists to this day; she has only made one Slam quarterfinal in the last (going on) five years.

Jankovic eventually wrested the top spot from her rival and went on a late-season tear to finish the year atop the rankings. A move to change her game in order to better compete for majors saw her not only remain slamless, but also caused her to tumble from the game’s elite.

This year’s Australian Open saw the two play one another for the first time at a Slam since that fateful French Open encounter. Far from the penultimate round, the rivals were seeded outside the top 10 and competing for a spot in the fourth round, where the winner would take on the much-higher ranked Agnieszka Radwanska.

Ostensibly, the stakes were as high as ever as each woman strives to retain relevancy on a Tour that has moved on without them. Once highly marketable stars, the rivals were relegated to Hisense Arena for a competitive, though more lighthearted, battle. While showing flashes of their former brilliance, the two shared a laugh several times during Ivanovic’s two-set victory. With that, the “Serbian Sisters” wordlessly confirmed the news that they had buried the hatchet.

Reflecting on their frosty past, Jankovic mused, “Back then we were competing for No. 1 and we both wanted what we never achieved and it was different circumstances.” In the heat of the moment, it was easy to see things less clearly, but in retrospect, Jelena poignantly describes the fate of the rivalry with her compatriot, one that was never truly realized.

But rather than dwelling on what might have been, it is comforting to see the two former foes together, now able to laugh and reminisce about their time at the top.
